I don't think there is one available at the moment. I have an Epson R200 (not all-in-one) that prints direct to CD/DVD and does a good job. You have to buy "printable" media though. Ordinary blank CDs and DVDs won't work, the ink doesn't dry.

as you can see they are quite expensive, personally I have an Epson CX3200 multifunction and a Canon Pixma ip3000 for disc printing both on one PC and I have got to say that the Canon is far better for disc printing than the Epson. I had an Epson R200 which now sits on top of the wardrobe the Canon runs rings round it far superior
